Description

Technical Field

[0001] The utility model relates to the technical field of plate bending, in particular to an anti-offset plate bending device. Background Technique

[0002] Plate bending is a metal processing technology. It refers to applying an external force to a metal plate through the use of specific tools or equipment (such as a bending machine) to make it bend and deform along a certain straight line or curve, forming a bent structure with a certain angle or shape.

[0003] Chinese Patent with the publication number CN219335486U discloses a numerically controlled bending machine that can prevent offset. By setting an upper fixing block, an upper lead screw, an upper lead screw sleeve, a lower fixing block, a lower lead screw, a lower lead screw sleeve, positioning vertical rods, etc., turning the lower lead screw by a knob, then driving a small gear to rotate by the lower lead screw, the small gear drives a large gear to rotate, and then the upper lead screw and the lower lead screw rotate synchronously. Through the synchronous rotation of the upper lead screw and the lower lead screw, the upper lead screw drives the upper lead screw sleeve to rotate and slide in the upper fixing block, and the lower lead screw drives the lower lead screw sleeve to rotate and relatively slide in the lower fixing block. The positioning vertical rods are driven to move synchronously by the upper lead screw sleeve and the lower lead screw sleeve, so as to clamp and position the bending plate through the positioning vertical rods, realizing the front and rear anti-offset of the bending plate. The bending plate is clamped and positioned up and down by the lower supporting roller and the upper pressing roller, so as to realize the up and down anti-offset of the bending plate. Through this set of devices, the front and rear positioning anti-offset of the plate is effectively improved, the bending quality is improved, and the friction generated by positioning is reduced.

[0004] However, the above solution lacks an effective anti-rebound device. After the plate is bent and the entire operation process is completed, due to the lack of a special anti-rebound structure to contain and restrain, the bent plate is very likely to rebound, rebound a part of the angle, and generate deformation, so that the originally expected bent shape and angle cannot be well maintained, thus affecting the final processing quality and product effect.

[0005] Therefore, it is very necessary to invent an anti-offset plate bending device. Content of the Utility Model
